The elevated departures ramp at the airport is also closed due to an accumulation of ice.

Travelers are asked to check with their airlines directly for the latest information on cancellations throughout the day.

The terminal remains open in a limited capacity, with limited food and beverage options. Lots of people sitting around the airport, waiting for the very latest. We talked to some of them about their traveling horror stories!

"We were supposed to leave yesterday and that got canceled. We got a new flight this morning, and that got canceled. And now we got a direct at least, but that was supposed to leave a half hour ago, and so we're still waiting," said Ed Demafiles, traveling home to Denver.

"We got here at 5 AM and got through security once. Our baggage was returned to baggage claim so we had to go back to claim that, and now we're sitting here, at the entrance, enjoying our couches," said Gabriel Paul, traveling home to Denver.

"I'm going to Vegas to get out of the cold, got on the plane at about 5:15 and they said get off the plane. We're not going anywhere. I wanted to go see Cher so bad tonight! So I'm missing my Cher!" said Deborah Laurent, from New Orleans traveling to Vegas.

"So you come prepared because the bars are not open this early, and they usually close around 10. So luckily, I had old Jack to keep me comfortable today," said Scott Pharis, traveling home to Texas.

More updates are expected throughout the day on the condition of the runways and the availability of flights.
